However, the written contracts alone are unlikely to provide all the information necessary to perform a transfer pricing analysis, or to provide information regarding the relevant contractual terms in sufficient detail. Further information will be required by taking into consideration evidence of the commercial or financial relations provided by the economically relevant characteristics in the other four categories (see paragraph 1.36): the functions performed by each of the parties to the transaction, taking into account assets used and risks assumed, together with the characteristics of property transferred or services provided, the economic circumstances of the parties and of the market in which the parties operate, and the business strategies pursued by the parties. Taken together, the analysis of economically relevant characteristics in all five categories provides evidence of the actual conduct of the associated enterprises. The evidence may clarify aspects of the written contractual arrangements by providing useful and consistent information. If the contract neither explicitly nor implicitly (taking into account applicable principles of contract interpretation) addresses characteristics of the transaction that are economically relevant, then any information provided by the contract should be supplemented for purposes of the transfer pricing analysis by the evidence provided by identifying those characteristics.
